PROBLEM TO BE SOLVED: To increase the photoelectric energy transduction efficiency by increasing the photocurrent of a solid-state solar battery, using an organic semiconductor. SOLUTION: A sandwich type laminate is formed of a p-type organic semiconductor thin film 2 and an n-type inorganic semiconductor thin film 4 across a coevaporated composite film 3, composed of a p-type organic semiconductor and an n-type inorganic semiconductor. On the p-type organic semiconductor thin film 2, a metal electrode 1 is formed and on the n-type inorganic semiconductor thin film 4, a transparent electrode 5 is formed. Irradiation with the sunshine from the side of the transparent electrode 5 causes the electrode 1 to generate a positive photoelectromotive voltage to the electrode 5, and a photocurrent is generated in the battery in a direction, where electrons flow from the electrode 1 to the electrode 5. |
